Modulair 105-107-112 air service equipment for use in potentially explosive at-
mospheres caused by gases, vapours, mists and/or dusts - ATEX 94/9/EC
AJF: 3834708 - A
MS P710-14
GENERAL
These Installation and Maintenance Instructions for
MODULAIR 105-107-112 air service equipment are
a general supplement to the specifi c Installation and
Maintenance Instructions for MODULAIR 105-107-112
air service equipment. Always use both I&M sheets for
installing and maintaining the cylinders.
DESCRIPTION
Essential Health and Safety Requirements:
MODULAIR 105-107-112 air service equipment is
designed in accordance with Annex II of the European
Directive 94/9/EC and standards EN 13463-1 and EN
13463-5.
Classifi cation (zones 1 and 21):
II 2GD c IIB T85 °C (T6)
or II 2GD c IIC T85 °C (T6)
INSTALLATION
Special conditions for safe use:
ASCO NUMATICS components are intended to be used
only within the technical characteristics specifi ed on
the equipment or in the Installation and Maintenance
Instructions.
Ground continuity:
Since the surfaces of most of the metal parts of our air
service equipment have been treated with a coating
which is isolating, it is necessary to locally remove the
coating to ensure ground continuity and check all me-
tal parts which come into contact with each other for
ground continuity.
All metal or conductive parts must be interconnected
and grounded.
Reminder: The inlet pressure ratings are limited in
accordance with ambient temperature (see Installation
and Maintenance Instructions for each piece of air ser-
vice equipment).
The installation must be carried out in accordance
with the requirements described in the Installation and
Maintenance instructions.
The air service equipment is designed to be installed
in potentially explosive atmospheres caused by gases
and/or dusts of Group II, Category 2GD.
In the case of air service equipment equipped with a
plastic bowl and a metal protector, check to make sure
that the metal protector is always in place.
The surface temperature classifi cation of 85°C depends
on the ambient temperature indicated on the piece of
equipment or in the Installation and Maintenance Ins-
tructions.
The chemical compatibility of the materials of the MO-
DULAIR 105-107-112 type air service equipment must
be verifi ed for the intended use.
In case a lubricator is used, it is recommended to
make sure that the oils used are compatible with
the atmospheres and temperatures indicated on the
equipment or in the I&M sheets.
MODULAIR 105-107-112 air service equipment is
equipped with air and condensate drains, it is therefore
recommended to channel the discharges for exhaust
into the atmosphere, if necessary.
The assembly of a MODULAIR 105-107-112 type air
service component to another component of the same
family does not constitute an additional explosive
hazard.
CAUTION
The equipment must be used within the limits defi ned in
the installation and operating instructions. Failure to stay
within the mechanical limits of the equipment will result
in damage to or premature failure of the equipment. This
will also invalidate its approval for use in dusty and
gaseous atmospheres.
MAINTENANCE
Before and during any work on the plastic bowl (clean-
ing, replacement, fi lling etc.), make sure that no explo-
sive atmosphere is present.
For servicing, refer to the installation and operating
instructions for MODULAIR 105-107-112 air service
equipment.
DISASSEMBLY / REASSEMBLY AND OIL FILLING
OF AIR SERVICE EQUIPMENT
This operation must be carried out by suitably qualifi ed
personnel.
In the case of air service equipment equipped with a
plastic bowl and a metal protector, make sure that the
metal protector is properly in place and ensure ade-
quate earth continuity is maintained between the bowl
and the body.
CAUTION: Depressurise the equipment and - if
necessary - turn off the electrical power before any
intervention.
Wrong assembly will invalidate the approval.
In case of replacement of parts by the user, the
traceability of the fi nal product cannot be guaranteed
by ASCO NUMATICS and must be ensured by the
user.
